Scott,

Same here. I was discussing this with another board member last night via PM. Here's why that is. There are basically two types of scanner technology:

CIS (Contact Image Sensor) - these are good if you're only scanning flat items such as raw cards, photos, magazine articles, etc - items that lay flat, directly on the scanner bed.

CCD (Charge Coupled Device) - these are good for slabbed cards or anything that doesn't lay directly on the scanner bed. Yes, the plastic slab itself does, but the card is elevated from the bed because of the slab.

That's why if you're scanning a BGS/BVG card with CIS technology, it is blurry because the those slabs are so thick. Get a CCD scanner and the problem goes away.

So, anyone using a scanner with CIS technology may have to tweak the settings to get a good representation of the actual card.
